Automatic Button Restoration (ABR):
The ABR feature releases locked-down buttons
when the handset is restored. The buttons may
be preset without removing the handset from
the cradle.
(c)
Line Recall:
An amber-capped recall
button provides switchhook flash without
releasing the buttons.
(d)
Intercom:
Two buttons are dedicated to
the intercom feature.
These buttons are
located on the right end of the 10-button key.
These buttons may be converted in the standard
manner to provide signaling or may be used for
CO/PBX lines. However, CO/PBX lines when
terminated at these positions will not be
conferencable.

INSTALLATION
3.01
Assemble the required components to the
telephone set base.
Note:
On current production keys the cap
must be properly oriented to lock the cap into
the button.
3.02
Individual signaling may be provided by
converting a locking key button to nonlocking.
Remove the 812857738 (P-28E773) locking pin from
the button to be converted and modify per Table. B.
3.03

screw grommets and mounting screws are
provided for installation. The additional KS-8109L2
or KS-20419L1 buzzer must be ordered separately.

Dial Restriction:
(1) 830-Type Telephone Set:
(a) Install a 533K (preferred), KS-21765Ll,
or 446F diode between terminals RR and
F of the network as shown in Fig. 6.
(b) Wire telephone set as shown in Table C.
(2) 2830-Type Telephone Set:
